9 # removal of the '2.' prefix from the Solaris version number.
10 # (Configure tries to detect an old fixincludes and needs
13 # If perl fails tests that involve dynamic loading of extensions, and
14 # you are using gcc, be sure that you are NOT using GNU as and ld. One
15 # way to do that is to invoke Configure with
17 # sh Configure -Dcc='gcc -B/usr/ccs/bin/'
19 # (Note that the trailing slash is *required*.)
20 # gcc will occasionally emit warnings about "unused prefix", but
21 # these ought to be harmless. See below for more details.

119 NOTE: Your system does not have /dev/fd mounted. If you want to
120 be able to use set-uid scripts you must ask your system administrator

163 GNU utilities or you must ask your system administrator to disable the
164 set-group-id bit on GNU make.
